BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a waning device for generate a safety signaland, more particularly, to a warning device which is mountable either ona stroller frame or a safety seat for generating the signal while thesafety seat is safely connected with the stroller.

2. Description of the Related Art

Stroller and car seat becomes a necessity to every family having aninfant or baby. The conventional foldable stroller is considered as aconvenience tool to carry the baby or young child during outdooractivities such as foot traveling and shopping. According to rules andregulations, the car seat must be employed in every vehicle fortransporting the baby or young child. Therefore, the stroller and thecar seat play the main role for the parents to carry their babies.

However, it is a hassle for the parent to move the baby back and forthfrom the safety seat to the stroller. Especially when the baby fallsasleep, the parent may merely wake him or her up while moving him or herfrom/to the safety seat to/from the stroller. Once the baby wakes up,the parent may take longer time to soothe him or her back to sleep.

Therefore, the parent may put the safety seat on the stroller so as tocarry the safety seat and the stroller at the same time. In U.S. Pat.No. 5,676,386, a baby stroller is provided with an engaging device forthe parent to move the baby from the car to the stroller without wakingup the baby. As the engaging device is a complex mechanism, the usercannot make sure whether the safety seat has been safely engaged to thestroller.

SUMMARY OF THE INVENTION

To overcome the shortcomings, the present invention intends to provide awarning device to help the user to make sure the safety of theengagement between the safety seat and the stroller.

A warning device according to the present invention includes a safetyseat, a baby stroller frame and an electronic device. The safety seathas a seat body, a handle and a pair of connecting elements; the babystroller frame has a connecting base provided with a pair of receptaclesadapted for engaging with the connecting elements. In addition, theelectronic device has at least a signal generating element, a battery,electronic circuit and at least a first touching switch received ineither one of the receptacles or the connecting elements for generatinga safety signal when the connecting elements is fully inserted into thereceptacles. It is to be understood that both the foregoing generaldescription and the following detailed description are exemplary andexplanatory and are intended to provide further explanation of theinvention as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 to 4, an embodiment of warning device according tothe present invention includes a safety seat 2, a baby stroller frame 3and an electronic device 4. The safety seat 2 has a seat body 21, ahandle 22 and a pair of connecting elements 23.

The baby stroller frame 3 has a connecting base 31 provided with a pairof receptacles adapted for engaging with the connecting elements 31. Thebaby stroller frame 3 may further comprise a pair of opposed sideportions 32 for installing the electronic device 4 which has at least asignal generating element 46, a battery 45, and electronic circuit (notshown) and at least a first touching switch 42 which is receivable ineither one of the receptacles 311 or the connecting elements 23 forgenerating a safety signal when the connecting elements 23 is fullyinserted into the receptacles 311.

In this embodiment, the first touching switch 42 is mounted inside thereceptacles 311. The connecting elements 31 each comprises a plug 231for inserting into the receptacles 311 so as to connect the safety seat2 to the baby stroller frame 3. While the plug 231 is fully insertedinto the receptacles 311 and touched the first touching switch 42, thesignal generating element 46 is generating a safety signal for showingthe connection between the plug 231 and the receptacles 311 has beensafely completed.

Preferably, the handle 22 may formed with a pair of latch 232 forlocking the safety seat 2 to the baby stroller frame 3 that prevents theplug 231 leaving the receptacles 311. Referring to FIG. 2, the handle 22is rotatable and positionable by a positioning mechanism 24. The handle22 can be positioned in an accessible position 10, a securing position20 and a supporting position 30. Referring to FIGS. 2 and 5, while thehandle 22 is rotated from the accessible position 10 to the securingposition 20, the latch 232 is relatively rotated to a position thatlocks the safety seat 2 to the baby stroller frame 3.

Oppositely, when the handle 22 is rotated and positioned in theaccessible position 10, the latch 232 is relatively rotated to anunlocked position, this permits the safety seat 2 to be moved from thestroller frame 3. Further, when the handle 22 is rotated and positionedat the supporting position 30, it would help to steady the safety seat 2against a possible rocking.

Persons of ordinary skill in the art will appreciate that the connectingbase 31 may be formed with a pair of latching slot 312 as shown in FIG.3 for engaging with the latch 232.

Referring to FIG. 4, the electronic device 4 may further comprise acontrol panel 41, a power switch, and a second touching switch 43 whichinstalled inside the latching slot 312. While the latches 232 is fullyengaged into the latching slot 312 and touched the second touchingswitch 43, the signal generating element 46 is then generating a safetysignal, for instance a sound or light for showing the engagement thereofhas been safely completed.

Persons of ordinary skill in the art will further appreciate that,although in the preferred example, the first and second touching element42 and 43 are connected inside the receptacles 311 and the latching slot312, but either could alternatively be installed at the plug 231 and thelatch 232 for showing the safety seat 2 is safely connected to the babystroller frame 3.
